Computer Network and Oprating System


Computer Network and OS
 
For desktop systems, access to a LAN or the Internet has become such an expected feature that in many ways it's hard to discuss an operating system without making reference to its connections to other computers and servers. Operating system developers have made the Internet the standard method for delivering crucial operating system updates and bug fixes. Although it is possible to receive these updates via CD, it is becoming increasingly less common. In fact, some entire operating systems themselves are only available through distribution over the Internet.

Further, a process called NetBooting has streamlined the capability to move the working operating system of a standard consumer desktop computer - kernel, user interface and all - off of the machine it controls. This was previously only possible for experienced power-users on multi-user platforms like UNIX and with a suite of specialized applications. NetBooting allows the operating system for one computer to be served over a network connection, by a remote computer connected anywhere in the network. One NetBoot server can serve operating systems to several dozen client computers simultaneously, and to the user sitting in front of each client computer the experience is just like they are using their familiar desktop operating system like Windows or MacOS.
 
Open Source
 
One question concerning the future of operating systems revolves around the ability of a particular philosophy of software distribution to create an operating system useable by corporations and consumers together.
 
Linux, the operating system created and distributed according to the principles of open source, has had a significant impact on the operating system in general. Most operating systems, drivers and utility programs are written by commercial organizations that distribute executable versions of their software -- versions that can't be studied or altered. Open source requires the distribution of original source materials that can be studied, altered and built upon, with the results once again freely distributed. In the desktop computer realm, this has led to the development and distribution of countless useful and cost-free applications like the image manipulation program GIMP and the popular web server Apache. In the consumer device realm, the use of Linux has paved the way for individual users to have greater control over how their devices behave.

Booting! What is this?

Booting! What is this? What is Booting? Booting  (booting up) is a bootstrapping process that starts operating systems when the user turns on a computer system. A boot sequence is the set of operations the computer performs when it is switched on that loads an operating system.   When you turn on the power to a computer, the first program that runs is usually a set of instructions kept in the computer's read-only memory ( ROM ). This code examines the system hardware to make sure everything is functioning properly. This power-on self test ( POST ) checks the  CPU , memory, and basic input-output systems ( BIOS ) for errors and stores the result in a special memory location. Once the  POST  has successfully completed, the software loaded in  ROM  (sometimes called the  BIOS  or firmware) will begin to activate the computer's disk drives. In most modern computers, when the computer activates the hard disk drive, it finds the first piec...
